Description
Atomfair-AFS863 Sensitive Enhanced Atomic Fluorescence Spectrometer
1. Instrument Features
- The main unit adopts an integrated modular design with a streamlined structure for easy operation and maintenance.
- Optimized excitation angle of light source and PMT, improving the receiving intensity of fluorescence signal, reducing background interference and significantly improving detection sensitivity.
- Equipped with an upgraded atomizer system, the atomization efficiency is greatly improved, the instrument sensitivity is enhanced, and the detection effect for mercury element is better.
- Equipped with a translucent corrosion-resistant magnetic suction front door, which can avoid interference caused by external air disturbance and observe the whole test process in real time.
2. Basic Functions
- Support single-channel detection and dual-channel simultaneous detection modes.
- With single-point, two-point, multi-point standard curve establishment function, and single-point, two-point standard curve correction function.
- Covers comprehensive sample introduction mode control functions such as continuous flow injection and traditional injection.
- Real-time observation of the test process, supporting online adjustment of three-dimensional parameters of the atomizer.
- Adopt pressure self-balanced waste liquid discharge design, no additional waste discharge pump is needed to ensure stable reaction.
- Optional fast intelligent automatic sampler to improve detection efficiency.
- Friendly software interface, can recommend the optimal instrument test conditions; support graphic display, playback, statistics and query of test data, as well as page saving, output, backup and printing of various graphics and data; suspended measurement window can increase the number of display information such as fluorescence intensity and blank value.
- Built-in instrument self-test and gas cut-off early warning protection function to ensure safe and stable operation of the equipment.
- Seamless connection with liquid phase and on-line digestion module to realize speciation analysis of arsenic, mercury, selenium and other elements.
